IKEYBOBD FOR TYPE-WRITING MACHINES.

Specicaton of `Letters Patent.

Application filed J'une 12, 1909. Serial No. 501,853.

To all l1J/1.0m it may concern:

Be it known that T,- 'r'ro PETERMANN, a citizen of the Republic of Switzerland, and a resident of New York, county and State of New York, have invented certain new and useful Improvement-s in Keyboards for Type-Writing Machines, of which the following is a full, clear, 4and exact description.

This invention relates more particularly to keyboards of a foldable front strike typewriting machine such as disclosed in the patent to F.l S. Rose, No. 754,24Q,dated March 8, 1904. l

rThe primary object of the invention is to provide simple and efficient key-levers and means :tor supporting said key-levers and other elements of a keyboard for typewriting machines.

A further object of the invention is to provide key-levers which have substantial bearings and which are arranged to be suspended from a support, and which keylevers may be each made of a single piece.

With these and other objects in view, the invention will be hereinafter more particularly described with reference to the accompanying drawings, which form a part of this specification, and will then be pointed out in the claims at the end of the description.

In the drawings, Figure l is a longitudinal section, partly in elevation, of one form of machine embodying my invention. Fig. 2 isa plan view, partly broken away, show ing one arrangement of the key-levers and elements. Fig. 3 is a fragmentary transverse section, showing in front elevation,

the key-levers and supporting means therefor. Fig. 4 is a detail plan of the plate or member to which the key-lever springs are attached. Fig. 5 is a detail view of one oi the members for supporting the key-levers. Figs. 6 and 7 are detail views of one form of key-lever blank. Figs. 8 to 10 show a lever substantially the same form as in Figs. 6 and 7, except that the end for the finger piece is different; and Figs. 11 to 13 show the key-levers after the blanks have been properly shaped.

The metallic frame l, Figs. 1 to 3, of the machine is constructed and arranged in any suitable manner, and may consist of side members and an integral back member with head or member is under-cut to provide two an intermediate transverse horizontal bar 2 suitably fastened to the sides of the frame '55h and serving as a brace therefor, and a sec- A, ond transverse bar'2a at the front of the machine, the whole frame being constructed of sheet metal with rounded edges for the purpose of making the frame'ilight and 6() strong.

The key-levers 3, Figs. 6 to 8, may have finger pieces orkeys 4, and are each provided intermediate its ends with an ynpwardly-extending part 5.. This part 5 may 65 be integral with the body portion 6, and the whole lever may be stamped`v` from sheet f metal or other material for-strength and' cheapness. The levers are first stamped or otherwise made in the form shown in Fig.6, 70 in which the support 7 for the finger-pieces 4, and the part 5 lie in the same vertical plane as the body portion 6, and by means of dies or otherwise, the support 7 isbent at right anglesto the body portion 6, so as to extend on opposite sides of the upper' edge of the key-levers and in a horizontal plane. This support 7 is slottedat 8, Fig. 6, So as to form two members 9 and 10, so that when said members 9 and 10 are bent down-- ward as shown in Fig. 7, one member will extend on one side of the body portion 6 and the other on the opposite side of said body portion, thus forming a substantial and proper support for each linger button, key or piece, though if desired the supportmay be formed as shown in Figs. 8 to 10, in which the support is slotted `at .108L and then bent to the. position shown in Figs. 9 and 10. l

The upwardly-extending part 5 ot each key-lever is formed with a shank or portion 11, andis substantially T-shaped to provide a header suspendingmember 12. This notches 13. When the lever 'is finished, the head 12 is forced transversely of the body portion G, and its outer ends bent to make said head substantially U-shaped when viewed from above, so thatsaid levers may be readily and quickly hung or supported from a plurality of transversely-extending bars o1' members 14. These bars are located under and extend downward from the transverse bar let and are held between the sides of the machine frame, as shown bestin Figs.

' l25 and inner ends of 1 and 2.y The levers 3, have their heads 12 of such width that they may rest against each other in series accordingto the number of bars or members 111. .As shown 'there are three bars 14, and eachbaris providedv turned or hooked-edge v15 which is adapted to it in the notches 13 of the key-levers 3, so that said levers will be supported on substantially a knife edge distance to each side with an upwardly and at two points some of the body portion 6.

' Each key-lever a transverse the an aperture 'in a type-bar for each. key-lever.

slotted part 22 of and curved bracke of screws 24 or otherwise. bar 23 may-oe made in a solid piece, type-bar has vits, pintle means of an -angular bar or space-bar, or any o be pivoted to the plate a part 27 .is provided, adapted to enter While I support, said in as they No; 501,849, filed June 12, 1909.

From the in which each key-lever has lever may be made i piece; that each key-lever has a wide substantial bearing; that simple and efficient the levers; and that simple means is provided for i means are provided for supporting restoring the levers to their normal Having Athus described my invention, claim as new and desire to secure by Letters 1. In a typewriting machine, the combia bearing bar attached from opposite sides thereof, knife-edged bearings carried by the 3 is provided with an aperture on its under side in which is adaptedv --t`c "bei fastened one end of a spring 16, the other end of said spring being held to aprojecting part 17 stamped or t'orcedl from bar or plate 18 at the lower part of the machine, whereby the said levers may be restored to their normal position. The levers are provided with p which one end of a link 19 is held, the outer end of ,said link being pivotally held to a type-bar 20, there being These type,- bars are each pivoted at 21, Fig. 1, in a a transversely-extending t or bar 23 which is held to the rear of the machine frame by'means This bracket or and each held na slot or recess is normally held againstremoval by device 26.
